Im currently selling my Gravely 36" walk behind because i got out of the business. I've had the walk behind for 4 years now. It is belt driven and does a awesome job of cutting grass. I've never had any problems with it and it is pretty good shape. The muffler bracket is a little bent back i never fixed it because its not that bad, but all it would take is to bend it back a little the other way to make it straight. Also comes with a sulky, everything is a little dirty but i can clean it. It has 142 hours on it, i would like $2000.00 or OBO. Pick up only.PM me if you are interested.
